  4. Configuration Commands Cont’d • copy running-config tftp -- stores the current configuration from RAM on a network TFTP server • show startup-config -- displays the saved configuration, which is the contents of NVRAM • erase startup-config --erases the contents of NVRAM

  5. Pre 11 Configuration Commands • Unfortunately for the short term you need to know them • Config term configure from terminal • Write term transfer to NVRAM • Config mem • Write mem • Config net • Write net • Show config • Write erase

  11. Global Configuration • Router # Configure terminal • Router (config)# • One line commands • System wide commands • Enter mode • Router (config)# interface type port • Router (config-if)#

  12. Router Interface commands • Router (config-if)# media-type 10baseT • Router (config-if)# int & 0.1 point-to-point • LAB – practice commands

  13. Passwords • line console 0 -- establishes a password on the console terminal • line vty 0 4 -- establishes password protection on incoming Telnet sessions • enable password -- restricts access to privileged EXEC mode • enable secret password (from the system configuration dialog to set up global parameters -- uses a Cisco proprietary encryption process to alter the password character string

  14. Messages and Descriptions • Router (config)# banner mtod #Welcome to Cisco Semester 2# • Router (config-if)# description this is a fun class
